An Indonesian court denies Australian drug smugglers Andrew Chan and Myuran Sukumaran the chance to have another judicial review of their death sentences, meaning there is now nothing stopping their executions.

Andrew Chan and Myuran Sukumaran, two Australian members of the so-called Bali Nine drug smuggling ring, are to be among the next group to face an Indonesian firing squad, Indonesia's attorney-general says.

Megan Washington and Josh Pyke are among a group of high-profile musicians who will perform at a concert as part of a campaign to save Bali Nine convicted drug smugglers Andrew Chan and Myuran Sukumaran from the death penalty.
